CAB INET FOR. EXHlBlTlNG PHOTOGRAPHIC PICTURES, &

Specification forming part of Letters Patent No. 414,125, dated September 6, 1864; antcdated September 2, 1864.

To all whom it may concern.-

Be it known that I, J. A. THOMPSON, of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Improvement in Apparatus for the Exhibition and Preservation of Photographs and other Pictures and I do declare that the followin g is a full and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specificatiom'in which Figure 1 is a perspective view Fig. 2, a longitudinal section. Figs. 3, 4, and 6 are views representing the different modes of consiructin g chains and compartments for receiving and carrying the. pictures; Fig. 5, a perspective view of the reel. or double-headed roller to which the end of the chain of pictures is attached.

I construct a box or case of any convenient size proportioned to the size of the pictures to le exhibited, and of any preferred suitable material or form desired, being careful to construct the ease as far as possible air-tight, to do which I recess the lid into the case or box and exclude the air by the interposition of thin slips of india rubber orleather, or other suitable material, between the edge of the box and the recessed lid or cover, bringing the lid firmly down by means of rod G, as seen in section, Fig. 2, and button B, in perspective, inierposing between button B and top of lid, and in bottom between head of rod and bottom, a packing of rubber or leather, and the same between buttons A A and the lid or cover, which may perfectly exclude the air,

dust, and light from the box. An aperture of suitable size is provided for the exhibition of the pictures, which is closed by a pane of thick, clear, transparent glass, through which the picture may be seen, as shown at U, by vignette, giving the effect and a similar view as when examined in frame separate This plate of glass requires to be longer than the width of the aperture, so the card shall strike upon the glass as it is moved upon its surface. The glass is recessed in, so as to be on a plane with inside of case, and is cemented in air-ti ht with any suitable cement.

D D, Fig. 2, are two rollers, which may be made with orwithout heads, as shown at Fig.

0. These stand vertical, and arejournaled into the bottom of the case, near each end, dividing the space equal between rod G and end of case. The top axles, F F, are left square for receiving the buttons A A, which turn in lid as the rolls are moved by them.

H H show the attachment of the chain t upper and lower end of rollers.

E E are two small rollers, which may be journaled plain to bottom and top of the case or supplied with springs, which will press the chain against the glass as it passes in front of rollers E E.

Fig. 3 represents a chain composed of two strips of thin sheet-brass or other suitable metal, with wire soldered between, as seen at I I.-

C O in Fig. 3 are vignettes, showing the position and relation of cards when placed in chain compartments, being placed between the slips of sheet metal and held by them at top and bottom.

Fig. 4 represents a chain with metallic slips by rods of wire, with eyes or slots in each end,

through which the strips and tapes are pas ed. Fig. 6 represents thebestform ofchain. Brackets or loops of wire are soldered at the upper and lower edge of slips of metal, and placed apart the distance of the width of the card or picture to be carried, and tape of strong linen or silk glides through these loops, which may be of greater width than the other forms represented, and will retain them in place and more readily receive and carry the pictures. The ends of the chain holding the pictures is attached to their respective rollers and rolled toward the center with the face of the picture outward. Theyare readily placed in case by passing between rolls E E and the glass. The lower journals of rollers D I) are then placed in their steps in the bottom of the ease. The lid or cover is brought down close by means of the button B. The buttons A A are now placed upon shafts F F; the pictures are brought into view by turning the left hand button, A, from you and toward the right, which brings the pictures from the right-hand roller to the left, and by turning the righthand button, A, toward the left they are returned and wound upon roller D to the right-hand. The last compartment in the chain should be supplied by a card containing directions for rollers. The greater firmness of the metal strip serves to control the linen tape.

I disclaim the exhibition of one or many pictures within a box or case by means of reels and endlt ss rhainsoftape or like material,this being done in the 'stereoscope and like Wellknown devices.

WVha-t I do claim is 1'. The construction and arrangement of aphotograph cabinet in which photogi aphs and other pictures may be readily exhibited through a plain glass, and preserved from chemical and mechanical effects of air, light, dust, and handling.

2. An improvement in chain of compartments for receiving and carrying the pictures by using for back of the compartments a strip of sheet-brass or like metal, in combination with a tape or ribbon in the front of the cards, which gives the requisite elasticity to regulate their movement, the Whole being constructed and operated as described.
